*The values have been detected on the sea level at standard atmosphere. The thrust and consumption values may vary according to the air temperature and density.
**E5 means the petrol type that can be used. E5= unleaded petrol 95 octanes up to 5% of ethanol. This symbol is shown on all the petrol pumps in Europe.
The new engine has been designed and developed to give usability and versatility of use with the aim to offer more reliability and to reduce the service charges.
Polini Thor 260 has been conceived to be the ideal engine for long distance flights and it is a real “GT” one, which joins high performance with a smooth running for a versatility to show its best.
Fluidity and regularity are essential to enjoy long-distance flights. Polini Thor 260 is liquid cooled and it has been designed to offer a smooth, regular and progressive power output and in-flight comfort that has been increased thanks to the reduction of the vibrations through the balance-countershaft.
Flight safety and care in consumption
The Polini Thor 260 is born from the wish to manufacture a balanced “cruise” engine for a market demand of more reliability and low consumption. With its 21kg (radiator included), the new Polini Thor 260 engine grants a perfect compromise between stability and power. With its 36hp at 8000rpm Polini Thor 260 engine can offer 105kg of thrust with a 160cm propeller.
The consumption is of only 3,5 liters/h at 4500 rpm. which corresponds to about 30kg of static thrust, medium value for level flight.
The cooling of the Polini Thor 260 engine is granted by a compact radiator to have a lighter weight when taking off and a better flight aerodynamics.
Polini Motori has met the decision to maintain the same fixing system on all its range of Thor paramotors. Manufacturers may thus produce a frame to install the whole range, significantly reducing both the productions costs and delivery times. A point in favor of the pilots who can change Thor model without replacing the frame.
The Polini Thor 260 engine is equipped with electric starter together with the manual “Flash starter”.
The great compromise reliability/power gives the Thor 260 engine the maximum versatility and it can be installed on single seat or two seat trike and delta trike.
The new THOR 260 is available with two different gear reductions: 2.8 (recommended for propellers till 140cm) and 3.2 (for propellers longer than 140cm).
